Abstract

In this paper we construct an approach to extract the Wigner energy [Bw(N,Z)=-W(A)|N-Z|-d(A)δN,Zπnp] by using local mass relations, in the first-order approximation. We obtain W(A)=(42.7±1.2)/A MeV, d(A)=(28.7±1.5)/A MeV. By using the Wigner energies such obtained as well as empirical pairing and symmetry energies, the resultant binding-energy difference between the lowest T=0 and T=1 states of odd-odd N=Z nuclei is in good agreement with experimental data.
